Description

Technical Field

[0001] The invention relates to the technical field of electromechanical engineering, and in particular to a driving device based on the eddy current coupling principle. Background Art

[0002] Pet drinking water equipment, especially smart pet drinking fountains, has received widespread attention in the market in recent years. These devices are designed to provide pets with a cleaner and more hygienic drinking environment while facilitating management by pet owners;

[0003] However, when the existing pet drinking water equipment is powered on, there are safety hazards such as circuit damage or water pump leakage. Since the existing pet drinking water equipment does not adopt water-electricity separation measures, leakage may cause electric shock to the pet. Although the voltage of general pet drinking water equipment is low (such as 5V1A or 5V2A), which is not enough to pose a life threat to the pet, it will make the pet feel uncomfortable and may even cause the pet to be afraid of water and not like to drink water, thus affecting its health. In extreme cases, if the equipment is short-circuited or exploded, it may cause serious physical damage to the pet.

[0004] In order to solve the problem of possible leakage in the existing pet drinking water equipment when it is powered on, a driving device based on the eddy current coupling principle is proposed. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a driving device based on the eddy current coupling principle, which overcomes the deficiencies of the prior art and solves the problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a driving device based on the eddy current coupling principle, comprising a driving box, a water storage tank and a base, wherein the water storage tank is detachably mounted on the top of the driving box, the base is detachably mounted on the bottom of the driving box, a water collecting cover is fixedly mounted on the bottom surface of the inner wall of the water storage tank, a water inlet is formed on the water collecting cover, a rotating shaft is fixedly mounted on the inner bottom surface of the water collecting cover, a driven part is rotatably connected to the rotating shaft, a water supply pipe is connected to the top of the water collecting cover, a driving motor is mounted in the internal configuration of the driving box directly below the water collecting cover, and an active part is fixedly mounted on the output end of the driving motor;

[0007] A drinking water tray is clamped on the top of the water storage tank, a power supply interface is installed on the outer wall of the driving box, and an electric heater is fixedly installed on the inner bottom surface of the water storage tank on one side of the water collecting cover;

[0008] The active part is composed of a rotating disk 1 fixedly mounted on the output shaft of the driving motor and a plurality of permanent magnet blocks fixedly mounted on the upper surface of the rotating disk 1;

[0009] The driven part is composed of a rotating disk 2 rotatably mounted on a rotating shaft, a copper block fixedly mounted on the bottom of the rotating disk 2, and a turbine blade fixedly mounted on the top of the rotating disk 2.

[0010] The rotation of the rotating disk 1 also drives the permanent magnet block to rotate. The rotating permanent magnet block can generate eddy currents in the copper block. The eddy currents interact with the magnetic field of the permanent magnet block to generate torque, causing the rotating disk 2 to rotate with the rotating disk 1. The rotating turbine blades can drive the water inside the water tank to flow in from the water inlet and be transported upward to the top along the water supply pipe. The transported water flows through the water distribution tray and enters the drinking tray for the pet to drink water. When the water inside the drinking tray continues to increase and is higher than the limit plate, the water on the surface can pass through the limit plate and be filtered through the filter water hole before returning to the water tank to form a water circulation. Since the driving motor does not directly contact the water inside the water tank, it can effectively avoid the situation where the water body is charged due to leakage. The water body can also be heated by the electric heater to ensure that the water temperature is suitable, thereby improving the drinking experience of the pet.

[0011] As a preferred technical solution of the present invention, a docking seat is fixedly installed at the bottom of the driving box, and a docking column plugged into the docking seat is formed on the top of the base.

[0012] The base can be docked with the docking seat at the bottom of the drive box by means of the docking column, so that the base and the drive box can be docked and installed accurately.

[0013] As a preferred technical solution of the present invention, a cover plate is provided on the top of the drive box, a clamping sleeve is fixedly mounted on the cover plate, and a plug-in column engaged with the clamping sleeve is formed on the inner wall of the drive box.

[0014] As a preferred technical solution of the present invention, the rotating disk one is located directly below the rotating disk two, and the rotating disk one and the rotating disk two are concentrically arranged, and the water inlet is connected to the water supply pipe.

[0015] As a preferred technical solution of the present invention, the water tray and the water storage tank are concentrically arranged, and a limiting plate is formed on the inner bottom surface of the water tray.

[0016] The water tray can store a certain amount of water for pets to drink. At the same time, the limit plate can limit the maximum water level inside the water tray. At the same time, when floating objects appear on the surface of the water stored in the water tray, the limit plate can be used to introduce the floating objects on the water surface into the water filter hole, which can effectively maintain the cleanliness of the water.

[0017] As a preferred technical solution of the present invention, a water filter hole is formed through the inner bottom surface of the water tray inside the limiting plate, and the top of the limiting plate is higher than the inner bottom surface of the water tray.

[0018] As a preferred technical solution of the present invention, a water distribution tray is arranged and connected between the drinking water tray and the water supply pipe, a cylinder matching the water supply pipe is formed at the axis of the water distribution tray, and the cross section of the water distribution tray is arc-shaped.

[0019] As a preferred technical solution of the present invention, the permanent magnet blocks are arranged in a circumferential manner with equal spacing on the rotating disk 1, and the copper blocks are coaxially arranged on the rotating disk 2, and the positions of the permanent magnet blocks and the copper blocks correspond to each other.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The rotating disk 1 rotates and drives the permanent magnet block to rotate at the same time. The rotating permanent magnet block can generate eddy currents in the copper block. The eddy currents interact with the magnetic field of the permanent magnet block to generate torque, so that the rotating disk 2 rotates with the rotating disk 1. The rotating turbine blades can drive the water inside the water tank to flow in from the water inlet and be transported upward to the top along the water supply pipe. The transported water flows through the water distribution tray and enters the water tray for the pet to drink water. Since the driving motor does not directly contact the water inside the water tank, it can effectively avoid the situation where the water body is charged due to leakage.

[0022] 2. The limit plate can limit the maximum water level inside the water tray. At the same time, when floating objects appear on the water surface stored inside the water tray, the limit plate can be used to introduce the floating objects on the water surface into the water filter hole, which can effectively maintain the cleanliness of the water.

[0023] 3. The water can also be heated by an electric heater to ensure the water temperature is appropriate and improve the pet's drinking experience. BRIEF DESCRIPTION OF THE DRAWINGS
